(1) When you use the forced stop deceleration function
(a) Servo-on command (from controller) on/off
When the servo-on command is turned off, the servo lock will be released after Tb [ms], and the
servo motor will coast. If the electromagnetic brake is enabled during servo-lock, the brake life may
be shorter. Therefore, set Tb about 1.5 times of the minimum delay time where the moving part will
not drop down for a vertical axis system, etc.

Note 1. ON: The electromagnetic brake is not activated.
OFF: The electromagnetic brake is activated.
2. The electromagnetic brake is released after the release delay time of the electromagnetic brake and operation time of the
external circuit relay, etc. For the release delay time of the electromagnetic brake, refer to "HG-KN/HG-SN Servo Motor
Instruction Manual".
3. Give the operation command from the controller after the electromagnetic brake is released.
